okay, its simple found the solution in another thread (http://www.oscommerce.com/forums/index.php?showtopic=53436&st=220) QUOTE(sbizo @ Nov 11 2004, 06:33 AM) Fixing error "1062 - Duplicate entry '1' for key 1". I changed the column 'customers_group_id' from PRIMARY to INDEX in the table 'product_groups' and it seems to work now. I don't know if this is the correct way or if it causes any other problem though...

make it four.... no ideas yet why this happens?? :(
